Problemas y desventajas de esta estructuración son, entre otros:Problems and disadvantages of this structuring are, among others:
- El tubo de sillín, al ser recto y vertical, no esta alineado respecto al eje del pedalier, Io que disminuye drásticamente Ia eficiencia durante el pedaleo y Ia transmisión de fuerzas del conjunto ciclista-bicicleta.- The saddle tube, being straight and vertical, is not aligned with respect to the bottom bracket, which drastically decreases the efficiency during pedaling and the transmission of forces of the bicycle-bicycle assembly.
- Tres tubos soldados confluyen en el mismo punto, Io que provoca una excesiva concentración de tensiones que pueden provocar rotura catastrófica, y máxime cuando es una zona en Ia que confluyen fuerzas elevadas, puesto que soportan el peso del ciclista y su fuerza mientras pedalea. - Configuración excesivamente rígida y poco confortable. No existe concepto de ángulo de confort.- Three welded tubes converge at the same point, which causes an excessive concentration of tensions that can cause catastrophic breakage, and especially when it is an area where high forces converge, since they support the weight of the cyclist and his strength while pedaling. - Overly rigid and uncomfortable configuration. There is no concept of comfort angle.
El objeto del invento se refiere a un nuevo cuadro de bicicleta, que consta de un triángulo trasero unido a un cuadrilátero delantero de elementos tubulares, constando el cuadrilátero delantero de un tubo cabecero al que se unen un tubo superior aproximadamente horizontal y un tubo inferior inclinado; un elemento de cierre que se une inferiormente al tubo inferior y para ubicar el pedalier superiormente a un elemento de acoplamiento, el cual se une superiormente con el tubo superior y constando el triángulo trasero de unos tirantes superiores, unos tirantes inferiores y el elemento de cierre, que es curvo y cubre Ia rueda trasera de Ia bicicleta, y siendo el eje del elemento de acoplamiento aproximadamente coplanario con el eje de los tirantes superiores formando un ángulo (α) respecto al eje del tubo superior de valor igual o mayor que 120°: α > 120°.The object of the invention relates to a new bicycle frame, which consists of a rear triangle attached to a front quadrilateral of tubular elements, the front quadrilateral of a head tube consisting of an approximately horizontal upper tube and an inclined lower tube. ; a closure element that joins inferiorly to the lower tube and to locate the bottom bracket superiorly to a coupling element, which joins superiorly with the upper tube and the rear triangle consisting of upper braces, lower braces and the closure element , which is curved and covers the rear wheel of the bicycle, and the axis of the coupling element is approximately coplanar with the axis of the upper braces forming an angle (α) with respect to the axis of the upper tube of value equal to or greater than 120 ° : α> 120 °.
En Ia zona de unión del elemento de acoplamiento con el tubo superior se dispone un tubo de sillín cuyo eje pasa por el centro del pedalier.In the connection area of the coupling element with the upper tube there is a saddle tube whose axis passes through the center of the bottom bracket.

- Existen tres porciones de tubo bien diferenciadas que constituyen junto al resto del triangulo delantero una misma y única pieza (construcción monocasco), fabricada en material compuesto de carbono, Io que reduce considerablemente el riesgo de rotura catastrófica en Ia zona del nudo de sillín, ya que no existen encuentros entre tubos ni cordones de soldadura que debilitan Ia estructura y concentran tensiones. Por Io tanto se puede afirmar que es una construcción mas sólida y duradera que las conocidas.- There are three well-differentiated tube portions that constitute the same and unique joint with the rest of the front triangle piece (monocoque construction), made of carbon composite material, which considerably reduces the risk of catastrophic breakage in the area of the saddle knot, since there are no encounters between tubes or welding cords that weaken the structure and concentrate stresses. Therefore, it can be affirmed that it is a more solid and durable construction than the known ones.
- Existe un ángulo de confort (α) formado entre el eje (β2) del elemento de acoplamiento (A) y el eje (β3) del tubo superior del cuadro.- There is a comfort angle (α) formed between the axis (β2) of the coupling element (A) and the axis (β3) of the upper tube of the frame.
- Existe un ángulo de acoplamiento (β) formado entre el eje (e2) del elemento de acoplamiento (A) y Ia recta, que une el centro del pedalier con el punto de intersección entre dicho eje (e2) y el arco interno del elemento de cierre.- There is a coupling angle (β) formed between the axis (e2) of the coupling element (A) and the straight one, which joins the center of the bottom bracket with the point of intersection between said axis (e2) and the internal arc of the element of closing.
- Estos ángulos (α), (β) mejoran e incrementa el confort del ciclista durante el pedaleo, permitiendo cierto grado de flexión y absorción de vibraciones. Ambos ángulos (α), (β) pueden variar preferentemente unos 5o desde Ia talla menor a Ia mayor para mantener el ratio rigidez-amortiguación-absorción de vibraciones constante e independiente del peso y talla del ciclista.- These angles (α), (β) improve and increase the comfort of the cyclist during pedaling, allowing some degree of flexion and vibration absorption. Both angles (α), (β) can preferably vary about 5 or from the smallest to the greatest size to keep the stiffness-damping-vibration absorption ratio constant and independent of the rider's weight and size.
